BICYCLE-SADDLE SPRING.

Specification of Letters Patent.

Patented March 10, 1908.

To all whom it may concern:

Be it known that I, MILLER M. DEEM, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Im rovements in Bicycle-SaddleSprings, of which the following is a specification.

This invention relates to improvements in bicycle saddle springs, andthe object of the present device is to provide an attachment y means ofwhich the strain is removed to a point remote from the bolt whichsecures the spring to the pommel while still retaining the properresiliency at the forward end of the saddle. There are several reasonsfor thus removing the strain. First, it reduces very materially, thechances of breaking the pommel at this, its weakest point, and also thatit provides a movement of the forward end of the saddle not heretoforeobtained.

Heretofore the forward end of the spring has been secured to .the saddleat the oint where the bolt entered the pommel. Mg object has been toremove the point of connection from this oint, because it is necessarilyweakened by t e bolt hole and I have provided an attachment to thespring whereby the forward end of the spring is given a pivotal ormovable connection with the saddle the forward end of the saddle isgiven the roper resiliency and the point of connection between thesaddle and spring removed from the point where the bolt enters thepommel, preferably to the rear thereof and nearer thecenter of thesaddle. This attachment consists of a plate of metal, capable of beingadjustably secured to the pommel and having an eye in its rear end inwhich the forward end of the truss spring is pivotally secured. Theinvention is more fully described in the following specification andclearly illustrated in the accompanying drawing, in which Figure 1 is acentral longitudinal sectional view of a saddle with my inventionapplied thereto. Fig. 2 is a plan view of the forward end ofthe springwith the saddle removed.

The numeral 1 designates the saddle and 2 the pommel thereof. The usualrear springs 3 are used and to these I secure the truss spring 4. Theforward end of this truss spring is bent to form two loops 5'and is thenbrought back to a point approximately in line with the center of thesaddle. At this point 6 it is engaged, pivotally, by the end of a plate7. This plate 7 is secured to the under side of the pommel by means ofthe bolt usually usedfor securing the forward end of the truss spring.This plate consequently forms what may be said to be a part of thepommel, at the same time the connection of the spring to the pommel isremoved to the'point 6, considerably to the rear thereof and away fromthe bolt which holds it to the pommel, where the plate is formed with aneye 8 and in this eye, the end of the spring is pivoted, and thispivotal'connection allows a very considerable movement of the forwardend of the saddle, while any jolt or strain to which the pommel issubjected is removed to this point 6.

It will be seen that with this construction of truss spring the forwardend of the saddle is allowed considerable room for vertical movement,which has been almost wholly unobtainable where the spring has beensecured to the pommel directly at the bolt. In this case it has beennecessary to depend on the compression of the forward coil or loop ofthe truss spring for any resiliency obtained; With my construction themovement is obtained through the spring of the socalled tongue 9 formedby the end of the truss spring in its return from the forward curve, tothe point of its pivotal connection to the saddle thus allowing amovement not obtainable where the spring is formed with a completeconvolution at the forward end.

Having thus fully described my invention what I claim and desire tosecure by Letters Patent is In a bicycle saddle spring, a truss springM. M. DEEM.
